need opinion on new changeout.

I recently installed a new system at my fathers house in Florida. Its working good but Im not sure if I got it at its maximum efficiency.
I installed an AEPF30361BA variable speed air handler with a GSX13O36 condenser. R410a. The air handler is an 06, but I changed out the evap for a 410a direct replacement from Goodman since the old one was r-22 only.

I have set the blower speed dip switches for 3.5 ton blower speed with minus 15% trim.

Its 82% outside as per google for this area. But I cant measure it inside either. Any way I can make a wetbulb thermometer myself? I heard a regular thermometer wrapped with wet cotton in the retunr box.

You have a thermometer. Now you need is the clean white shoe string. Insert the thermometer into the shoe string. Wet it. Leave it on the table and watch the temp rise until it stops. (the pint when it goes up & down. NOW you got wet bulb.
